I've had some partial success, after fiddling around with my
config options. Adding more debug output gives activity on the
serial port, but still nothing on the display and no beeps, or
reactions from the keyboard.

Attached are both my current .config and the output generated
over the serial line, as captured by minicom on another machine.

This is from an ASUS M2V motherboard, with an AMD Sempron 2800+
CPU (family 15, model 79, stepping 2 according to /proc/cpuinfo),
two Kingston KVR667D2N5K2/2G memory sticks (total 2GB RAM), and
an ASUS EAX300LE-A334C/TD (EAX300/TD/P/128M/A) graphics card (I
have also tried with an old ATI PCI MACH64 card from 1996, no
difference).

If anyone could tell me what I'm doing wrong, or at least what I
should try next, I'd be grateful.
